ELECTRICAL GOVERNOR FOR GAS-ENGINES.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed September 5, 1907. Serial No. 391,500.

' iull and clear description, reference being had to the accompanying drawing, in which .Flgure 1 IS a vertlcal sectional view of my improved governor, and Fig. 2 an end view thereof.

This invention has relation to that class of governors for internal combustion engines in which means are embodied for breaking; the ignition circuit upon the attainment of an abnormal speed and thus prevent the charge .being. ignited, and it is especially designed for use in connection with an engine provided. with means for retaining in the cylinder each charge until it isexplodcd, thus accomplishinga material saving in fuel and avoiding the danger and nuisance of ejecting unburned charges into-the atmosphere, as more fully hereinafter set forth. Referring to the drawing annexed by reference characters, a designates the main shaft of the engine and b a portion of the hub of the fly-wheel affixed thereto. Mounted on the shaft adjacent to the hub is a sleeve 0 which is adapted to be rotatably adjusted on said sleeve to advance or retard the sparking, any suitable means being employed for ro-' tating the sleeve and locking it in its adjusted position. I prefer using for this purpose a rod (1 pivotal y connected to a lug depending from the sleeve and having at its other end a slot by meansof which and a suitable nut and bolt.-the,,-,rod may be locked at any point of adjustment to a suitable part of the engine frame. Bolted insulatedly upon the upper side of this sleeve is a plate e which at its inner edge is provided with an upturned flange f whose upper edge is curved concentrically with the shaft of the engine and is adaptedto afford a contacting surface for the rotating element of the device.

Bolted by means of a bolt g and a nut h to the adjacent edge of the hub is a metal bracket i, suitable insulation being providcd to insulate this bracket from the hub.

Projecting from this bracket outwardly overincloses a contact ball m, a spiral spring a,

and a screw plug 0. A s ring presses the" ball toward the inner end 0 the tube and the plug enables the tension of this sprin to be adjusted. The. bore of the tube is s igh'tly narrowed at its inner ,ez'ctremit'y so as to permit the ball to protrude a short distance beyond the inner end'of the tube.

The bolt 9 is extended radially a considerable distance to form a guide rod 1) for a governor weight g, and this governor weight is normally pressed inwardly b a coiled spring 1 1 whose tension may be regu ated by a nut s.

This weight is normally pressed against an integral arm 2! of the bracket *5 through a hole in which armthe guide rod extends without touching the arm.

The conductor of the ignition circuit is connected to plate e by a suitable bindingpost, such as u, so that when the contact ball m. rolls over the contacting-face of-the. flange f sleeve, the bracket'i and its arm t, and thence and thus ,break contact between it and the insulated bracket 71 and thus prevent the sparker from igniting the charge.

Having thus fully described my invention, what I claim as new and desire to secure 1) Letters Patent, is

1. In an internal combustion engine, the

combination of a sleeve rotatably mounted on the shaft of the engine, means for rotatably adjusting and locking this sleeve, an insulated contact member mounted on this sleeve and having a curved contact face, and automatic circuit-breaking means mounted on the adjacent hub of the fly-wheel and comprising a bracket and means for bolting it insulatedly to the hub, this bracket being provided with an arm, a tube mounted on this arm and adapted to be radially adjusted, a ball contact piece protruding from the. inner end of the tube, a spring and an adjust able plug for hearing on said ball contact, and a governor weight normally in circuit with said bracket and sleeve. 9

2. The combination an internal combustion engine, of one contact member 75 the current will pass through the ball, the" mounted rotatebly on the Shaft of the engine edj ecent to the fly-Wheel, a metallic bracket end a bolt for fastening it to the periphery ot the hub of the fly-Wheel, said bolt being extended radially outward and carrying a governor Weight and an adjustable spring,

' the spring serving to normally press the governor Weight inwardly against part of the bracket, whereby the governor welght form's part of the ClYClllt, and. a contest member C10 Po ou yuue oerried by said bracket, substantially set forth.

In testrmony whereof i hereunto all signature 111 the presence of two W1 near this 28 da' of August 1907.
